Recently, several innovative devices have been proposed, such as the proximal femoral bionic nail, InterTAN, and medial buttress plate combined with cannulated screws, to increase the stability of fixation. However, the differences among these innovative devices need to be addressed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>This study aimed to compare the stability of the proximal femoral bionic nail, InterTAN, and medial buttress plate combined with cannulated screws for vertically oriented femoral neck fractures. Additionally, traditional fixation devices\u2014including three parallel cannulated screws, a compression hip screw system, and a proximal femoral nail\u2014were included for comparison, resulting in a total of six distinct devices evaluated in this study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A finite element model of a femoral neck fracture fixed with the six internal fixation devices was created. Furthermore, two different fracture conditions\u2014with and without a 1-mm fracture gap\u2014were considered. The maximum loading during level walking was applied to the model for comparison.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The results indicated that the InterTAN has the best ability to maintain the gap and prevent collapse. Under the fracture gap condition, the peak displacement of the femoral head was smaller in the innovative devices compared to the traditional ones. Specifically, the peak displacements were 1.98\u2005mm for the medial buttress plate combined with cannulated screws, 2.12\u2005mm for the proximal femoral bionic nail, and 1.16\u2005mm for the InterTAN system. The von Mises stress in the medial buttress plate was also the highest among the devices, with values of 1000 MPa with the gap and 1477 MPa without the gap.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Based on the present results, the medial buttress plate combined with cannulated screws, proximal femoral bionic nail, and InterTAN are recommended for cases without a fracture gap, while the InterTAN is recommended for cases with a fracture gap to prevent bone shortening.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09592989251414222","type":"journal-article","created":{"date-parts":[[2026,1,19]],"date-time":"2026-01-19T08:23:21Z","timestamp":1768811001000},"page":"93-104","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Finite element analysis of six distinct fixation devices for vertically oriented femoral neck fractures"],"prefix":"10.1177","volume":"37","author":[{"given":"Yen-Nien","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Asia university, Taichung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hsin-Chuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Show Chwan Memorial Hospital, Changhua, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang-Han","family":"Chuang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Show Chwan Memorial Hospital, Changhua, Taiwan"},{"name":"Department of Orthopedics, Kaohsiung Show Chwan Memorial Hospital, Kaohsiung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chih-Wei","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, College of Medicine, National Cheng Kung University, Tainan, Taiwan"},{"name":"Department of Orthopedics, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Hsuan","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Show Chwan Memorial Hospital, Changhua, Taiwan"},{"name":"Translation Medicine, College of Life Sciences, National Chung-Hsing University, Tai-chung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,1,19]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01623184"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197658050-00020"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5413.38574"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198466060-00003"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0020-1383(82)90049-3"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200408000-00015"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-021-01959-z"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11517-007-0258-y"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1080\/03093640008726534"},{"key":"e_1_3_2_11_2","first-page":"827","article-title":"Predictive criterions of unrecognized articular effraction after internal fixation of femoral neck fractures","volume":"82","author":"Karray M","year":"2004","unstructured":"Karray M, et al.
